16-0 Glossary: Every Term Explained

Every term you’ll see in 16-0, and the football records around it, explained in one place.

Game terms

16-0 — A perfect 16-game regular season: sixteen wins, zero losses. The goal of this game, and the record only the 2007 Patriots have ever reached in real life.

Spin — At the start of each draft round, the game “spins” to land on a random NFL era (a decade from the 1960s to the 2020s) and offers you candidates from it at that round’s position.

Draft — The nine-round process of building your roster, one player per position, from the candidates each spin produces.

Round — One of the nine draft steps. Each round is locked to a single position, so you always end with a complete team.

Reroll — A limited action (you get three per draft) that discards the current round’s candidate pool and spins a fresh one for the same position. Rerolls don’t refill.

Era — The decade a player comes from. Eras change how the sport plays — older ones reward the run and defense, newer ones reward the pass — and your roster’s overall era affects the simulation.

Era fit — A rating reflecting how well your roster’s players suit the era your team represents. A coherent, single-style roster fits better than a scattered one.

Chemistry — A modifier applied to your team based on how well your nine picks work together. Good chemistry raises your effective ratings; poor chemistry lowers them.

Overall rating — Your roster’s headline strength number, built from its offense, defense, pass game, run game, trenches, and era fit.

Trenches — The offensive and defensive lines. A trenches rating captures line play, which sets the floor for both the run game and pass protection.

Blind Draft — A harder draft mode where player ratings are hidden. You draft on names, positions, and instinct, and learn how good your roster is only when the season runs.

Seed — A short code that reproduces your exact draft. Share it and another player gets the same sequence of candidates, so you can run a mirror match or a head-to-head.

Daily Challenge — A shared mode where everyone who plays that day gets the identical draft sequence, so results are directly comparable on a public leaderboard.

Grade — A letter score (S, A, B, C, D, F) summarizing your run. An unbeaten 16-0 season earns the top grade.

Football records around a perfect season

Perfect regular season — Winning every regular-season game. Under the 16-game schedule (1978–2020) that’s 16-0; under today’s 17-game schedule it would be 17-0.

15-1 — One loss shy of a perfect regular season. Several great teams have finished 15-1 — the closest anyone can get to 16-0 without reaching it.

18-1 — The 2007 Patriots’ actual final record: 16-0 in the regular season, two playoff wins, and a loss in Super Bowl XLII.

17-0 — Two meanings: the 1972 Dolphins’ full perfect season (14-0 regular season plus 3-0 playoffs), or a hypothetical perfect modern 17-game regular season.

19-0 / 20-0 — Perfect seasons including the playoffs — 19-0 under the 16-game format, 20-0 under the 17-game format. Neither has been completed. See 16-0 vs 17-0 vs 19-0 for the full breakdown.
